Abstract: PURPOSE:To designate a region to be erased accurately, by setting discrete point on the curve surrounding the region to be erased from a hand-written picture and forming rectangles with lines, which pass through respective points and are parallel with the axis X, and segments which pass middles between respective points and are parallel with the axis Y. CONSTITUTION:In case that a part of a hand-written picture is erased, a closed curve C1 is described surrounding this region. Points P1-Pn (n=12 in figure) existing discretely on the curve are set, and lines m1-m5 which pass through respective points Pi and are parallel with the axis X are drawn. Next, segments l1-ln (n=8 in figure) which pass throuhg middles between adjacent points Pi and Pi+1 passing through adjacent points, thus forming rectangles. These rectangles are defined as erase sections; but if plural rectangles are formed between adjacent lines such as lines m4 and m5, these rectangles are defined as erase sections alternately. No segment l is generated between adjacent points having the same Y coordinates (such as points P4 and P5 and points P6 and P7). Thus, the length between points Pn is expanded or reduced in accordance with the pen speed to designate accurately the region to be erased.

Title: Semiconductor device and its manufacture
Inventor: SAYAMA HIROKAZU
IPC: H01L21/316
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To simultaneously improve the service life and operating speed of a semiconductor device and the ease of the manufacturing process of the device. SOLUTION: A high voltage element H, upon which a high gate voltage is impressed and a low-voltage element L upon which a low gate voltage is impressed are formed in a semiconductor substrate 1. Gate insulating films 7 and 17 contain bird's beaks 8 and 18 formed through thermal oxidation. Since the gate electrode 9 of the high voltage element H has a shorter gate length than the gate electrode 19 of the low-voltage element L has, the rates of the occupying area of the bird's beaks 8 and 18 in the gate insulating films 7 and 17 become low in the low-voltage element L and high in the high-voltage element H. Therefore, the service life of the high-voltage element H can be prolonged, because the breakdown voltage of the element H is increased and the time-dependent deterioration of the element H is suppressed.  In addition, the operating speed of the low-voltage element L is increased, because a high current drive capability is obtained.
